refactor(certgen): drop dead native logging code

Remove orphaned native logging that nothing reached:

- The /sdcard/Download zip dump (NativeCertGen.dump and the dumpLogs
  JNI, dump_logs_inner, dump.rs, pub mod dump), superseded by the
  diag.sh export.
- The verbose-marker helpers (sysfs.rs, pub mod sysfs); the manual
  .verbose toggle still works via mod.rs::init's inline check.

Drop the now-unused direct deps zip and libc and the orphaned jstring
import. cargo ndk build is warning-clean.
